Abstract:The application of high performance liquid chromatography (HPLC) technique in the hydrocarbon group analysis of oils, petrochemicals and coal-derived oils was reviewed. The progress indicated that HPLC had advantages of good and repeatable separation with fast speed in the hydrocarbon group analysis. Sample was properly separated by multidimensional HPLC which integrated with valve switching and gradient elution.Associated with a variety of detection methods, HPLC had wide application prospects in the hydrocarbon group analysis of oils.
